The following series implements changes to the Linux NFS server's
socket transport that are pre-requisite to supporting RPC on TLS.
The socket transport is made to use the iov_iter-based kernel
socket APIs. These changes are modeled after similar changes made
to the NFS client-side socket transport.
This is a draft patch series. I have tried it out and it is working,
but as it has changed only the Reply-send side, it is incomplete.
This posting is a request for comments -- show your work.
One additional change I might make in this series is moving the
xpt_mutex into the socket sendto methods. This is because the
RDMA sendto method doesn't appear to require serialization. That
is still down the road.
